Application July 16, 1952, Serial No. 299,457 7 Claims. (01. 160-90) Myinvention is particularly concerned with an improved type of combinedstorm and screen window construction incorporating a sash supportingframe having triple tracks, and it has for its general object a tripletrack combined storm and screen Window structure wherein screenedventilation is enabled through either the top or bottom of the structureor both without removal or replacement of any of the sash members.

In my invention an expansion frame adapted to be secured about a windowopening carries a sash encasing frame provided with three pairs of railsup and down which there is adapted to slide a pair of storm windowsashes and a screen sash. The screen sash serves to provide ventilationthrough the lower portion of the window opening; to have ventilationthrough the upper portion there is provided a smaller screen sash. Thislatter sash does not move vertically, but is arranged to move rearwardlyor forwardly of the encasing frame.

The invention, while it could well be used in lieu of the conventionaldouble hung windows of a building, represents an auxiliary structure fordouble hung windows, and it is intended to occuply that space in thewindow opening that exists between the regular window and the outside ofthe building. In its later use it provides many advantages, eliminatingmany defects associated with conventional storm and screen windowstructures.

Inserting or changing storm or screen sashes with the different seasonsis not required with my invention, as the storm and screen sashes arealready incorporated in the structure and are operable much in themanner of double hung windows. The screen sashes and the storm sashesmay be adjusted as desired and, regardless of the season, withoutremoving or replacing any of the sash members.

In the use of a structure embodying my invention ventilation may be hadthrough the window frame opening either at the top or bottom, or both;ventilation may also be out 01f entirely by the storm window sashes, ifdesired, particularly in cold weather.

The invention further lies not only in the various features whereby theforegoing advantages are obtained, but also in the novel arrangement andgeneral organization of its various co-operable elements.

The invention together with its many advantages will become readilyapparent as this specification unfolds in greater detail and as it isread in conjunction with the accompanying drawings 2 wherein a preferredand specific embodiment of the invention is illustrated. In thedrawings:-

Fig. 1 is a front elevational view of a combined storm and screen windowstructure embodying my invention;

Fig. 2 is a cross section taken .on the lines 2 -2 of Fig. 1;

Fig. 3 is a fragmentary View of part of a sash member;

Fig. 4 is a front elevation of the small screen sash;

Fig. 5 is a perspective view of the small screen sash illustrating thetop, rear and one side thereof; and

Fig. 6 is a sectional view showing the small sash displaced to itsmiddle position.

In detail, the invention includes an expansion frame I comprising upperand lower broad strips 2, 3 and a pair of upright broad side strips 4.The expansion frame is adapted to be aflixed in suitable manner, such asby fasteners 5 to the outside of a building about the conventionalwindow opening. The expansion frame serves to carry by proper means asash encasing frame 6. For this purpose a continuous channel 1 isprovided in the inner side of the expansion frame. In this channel thereis adapted to be received and contained a tongue 8 of the encasing framemember 6. To allow frame member 6 to be received by its tongue in theexpansion frame I, the upper strip 2 is preferably formed free of theuprights 4. In the assemblying process the tongue 8 on three sides offrame 6 is received in the channel 1 of the uprights 4 and the lowerstrip 3. Next, the strip 2 is placed in its proper position at the topto complete the frame, in such manner that tongue 8 of the upper side offrame 6 is contained in the channel 1 of the upper strip 2.

The sash encasing frame 6 further includes top and bottom cross walls 9,l0 and a pair of upright side walls I I, of which but one is shown, theother being identical, suitably joined to one another in the form of abox with open front and rear ends. Frame 6 is further provided to carryfor vertical sliding movement therein three sashes I4, I 5 and I6.Sashes I 4 and it are each closed over with a glass panel [1, while sashl6 carries a screen panel !8. Each sash member comprises upper and lowercross pieces I9, 20 and a pair of side pieces 2|. The lower cross pieceof each sash contains lifting means, such as a finger well, not shown.In each of the sash uprights 2| is a channel 23 by which each sash isguided for vertical sliding movement upon a separate pair of rails 24carried by the inner walls of the upright side members ll of frame 6.The outer pair of rails, those nearest to the expansion frame I, serveto guide one of the glazed sashes, here sash M; the middle pair of railsserve to guide the glazed sash [5, while the inner pair of rails guidethe screen sash l6.

Rails 24 are carried, three to each side, on the inner faces of wallsll. While the rails may be an integral part of walls H, or removablyinserted in'suitable manner in slots therein; here, however, they assumea different and preferred form. In this form there is provided for eachside wall H a pair of plates 21, 23. In each plate there is formed a setof three rails 24 parallel to one another and uniformly spaced apart.Plates 21, 28 of each pair are removably secured to the inner face ofeach side member H, one above the other, in such manner that the railsof the lower plate 28 are in vertical alignment with the rails of theplate 21 above it. The several rails of each side wall are of equalheight and extend from the base of the frame to a short distance fromthe top, leaving a space 29 without rails at the top of each wall ll.

Between the wall spaces 29 at the upper portion of frame 6 there isprovided to move rearwardly or forwardly of the frame, as desired,asmall sash member 30 having a screen panel 3 I. This small screenedsash occupies about onesixth of the opening of frame t, and it isintended to provide screened ventilation through the top portion of thewindow opening. Suitable means is provided to enable this rearward orforward movement of sash 30. It is guided in this crosswise by suitableCrosswise of the space 29 in each sidewall H is an elongated slot 32through which extends a pin.33 projecting one from each side of uprights34 of the small screen sash 3G. The sash is carried rearwardlyor'forwardly of slots 32 through spring means co-operable with theraising or lowering of the glazed sash members is and it. A pair ofcurved or s springs 35 affixed at one end to the top side of wall a andat the other end'to'the rear of sash uprights 3d serve to tension sash30 in an erect position constantly forwardly of frame 6. Sash 39 islimited in its forward movement to a position in alignment with andabove sash M by pins 33 abutting the forward ends of slots 32.

Glazed sashes I4 and 15 are of equal height and each. is adapted toclose off a half portion of the Window opening. Screen sash it couldalso be of .a height equal to one of the glazed. sashes, however, it isdesirable that sash it, when compin and slot means.

bined with sash 30 equal the height of one of the glazedsashes. Thesmallersash 3t is intended tOLPIOVldB screened ventilation through theupper portion of the window opening, while the larger sash 116 isintended to serve the bottom.

To. enable sash 3D to move rearwardly of frame 6 against the tension ofsprings 35, the lower crosspiece of sash 39 is adapted for cammingaction in conjunction'with either of the sashes i4, 1 5 or 16, wherebysash 39 may be progressively moved rearwardly. To effect this action,the bottom side 42 of the lower crosspiece of sash 3B is inclinedrearwardly from ahigh point on the. forward edge of the crosspiece to alow point on the rearward edge thereof; and the top side 43 ofthe uppercrosspiece l9-of each sash it, it and IG is inclined in a complementarymanner.

In explanation of the use and" operation of the structure reference isdirected particularly to Figs. 1, 2 and 6. The expansion'frame 'l isintended to attach to the outside of a building structure, while theframe 6 encasing the several sashes is intended to occupy the spacebetween the outside and the regular window of the building. In Fig. 2the small screen sash 3B is shown tensioned to its foremost positionabove the lower sash l4, and sash I5 is in its lowered position. To movesash 3B rearwardly so as to out 01f ventilation from thetop of thestructure, sash I4 is raised to bring the cam surface 43 of its uppercross piece against the complementary cam surface 42 of sash 30. Furtherand a .full raising of sash M will cam sash 30 rearwardly against thetension of springs 35 to assume aposition to the rear of sash M as inFig. 6. During the camming operation sash 30 is forced off the inclinedsurface of sash l4 and moves to the rear as it rises upwards in front ofit as in Fig. '6. Sash 30 is guided in its rearward movement by the pinand slot means 32, 33 at the sides thereof; It is plain that fullyraising the middle sash 15 will ina similar manner force sash 30 to itsrearmost position above screen sash l6. When sash an is in the latterposition with the two glazed sashes-l4 and I5 fully raised, screen sashIt may in a-lowered position provide screened ventilationthrough'the'bottom of the window opening. 7

It is plain from Fig. 6 that if the first sash I4 is lowered, springs 35will tension sash Sllback to its normal position.

When sash 3a is in its normal position, sashes l4 and [5 may be partlyraised and screen sash It lowered, whereby ventilation will be affordedthrough both the top and bottom of the structure.

Due to the slight separation of sashes M, 1-5 and Hi from one another,means is provided to prevent entrance of cold air, insects and otherforeign matter from between the sashes. This is enabled by a cross strip41 located along the rear marginal edge of sash 30, which stripoverhangs the sash below and to its rear.

When sash 3a is in its normal forward position and sash It is in itsfully lowered position, sash I5, the middle sash, may be raised untilits uppermost edge contacts the cross strip 41 of sash 30. In thisarrangement ventilation can be had solely through the sash 30 at the topof the structure. When sash M is fully raised so that sash 3B isdisplaced to its rear, and while sash I5 is in its lowered position,ventilation is .cut off entirely.

Thelower half of the window opening may be made fully open so as toprovide. free access through to the outside o'f-the building. This isaccomplished by successively and fully raising sashes i i and &5 so asto displace-sash 3!) to its rearmost position abovesash'i-B, and finallyby raising sash H5 until'it contacts sash 3i].

Conventional well known means; such as springs, not shownyinthe channels23 .of sashes l4, l5 and it serve in conjunction with conven tionalgrooves, not shown, in which they engage to tension and to hold thesashes in their various raised positions.

The various elements. of the structure are preferably fashioned oflight, stainless metalfsuch as aluminum or other suitable metal. l 'IWhile I have described what'I considerto'bc a highly desirableembodiment of'my invention, it is my intent, however, to claim'all suchforms OfthBlIIVELIItiOII as may bereasonably construed tob'e within thespiritof the invention .and with in'thescope'of'the appended claims.
